Determine the critical value LaTeX: z_{\frac{\alpha}{2}}z α 2 that corresponds to a 96% level of confidence.

The confidence level for this case is 96% or 0.96, then the significance level would be:

And then . We need to find a critical value who accumulates 0.02 of the area on each tail and we got:

Step-by-step explanation:

The confidence level for this case is 96% or 0.96, then the significance level would be:

And then . We need to find a critical value who accumulates 0.02 of the area on each tail and we got:

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
